Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to an automatic batching device for processing modified plastics. Background Art

[0002] Modified plastics refer to plastic products that are modified on the basis of general plastics and engineering plastics through filling, blending, reinforcement and other methods to improve the flame retardancy, strength, impact resistance, toughness and other properties. The modified plastic parts can not only achieve the strength properties of some steel, but also have a series of advantages such as light weight, rich colors and easy molding.

[0003] An automatic batching device for modified plastic processing disclosed in the Chinese utility model patent application disclosure CN217514295U, although the device described in the application can use a rotating rod to drive the stirring blade to uniformly stir the mixed material in the batching barrel, while stirring the mixed material, it can also synchronously make the mixed material move relative to each other in the batching barrel, and make the lower layer of material continuously flip to the upper layer, further improving the batching quality and preventing the occurrence of material stratification or material coagulation when standing still. However, during the batching process, the staff is required to prepare different amounts of engineering plastic particles and ensure that the size of these particles is qualified to avoid uneven mixing of particles of different sizes after melting. However, the preparation and screening processes are carried out separately from the batching device, making the processing process more complicated and greatly reducing the work efficiency. There is a disadvantage of low work efficiency. In addition, during the unloading process, if the materials in the storage box are unloaded too quickly, it is easy to cause bridging at the unloading port, making it impossible to unload normally, and there is a disadvantage of easy bridging during unloading.

The left end of the screening plate 17 is set at the through slot 23. The outer surface of the third rotating shaft 14 is fixedly connected to the auger blade 15. The lower surface of the other side of the conveying pipe 9 is provided with a feeding pipe 901. The upper surface of the mixing tank 1 is fixedly connected to the feeding channel 25. A circular tube 26 is provided in the middle of the feeding channel 25. The upper surface of the feeding channel 25 is fixedly connected to the second V-shaped funnel 24. The upper surface of the second V-shaped funnel 24 is fixedly connected to the screening box 16. A circular groove 27 is provided inside the circular tube 26. The end surface of the circular groove 27 is rotatably connected to the fourth rotating shaft 29 through a bearing. The outer surface of the fourth rotating shaft 29 is fixedly connected to the rotating roller 30. The surface of the rotating roller 30 is provided with a material trough 31. A servo motor 28 is installed on the outer surface of the circular tube 26, and the output end of the servo motor 28 is fixedly connected to the fourth rotating shaft 29. There are two material troughs 31, and a feed port 32 is opened on the upper surface of the mixing tank 1. The feed port 32 is connected to the feed channel 25. There are three storage boxes 7, and the circular array is distributed around the mixing tank 1.

[0031] In order to achieve the purpose of improving work efficiency, when in use, referring to Example 1, after the raw material enters the screening box 16 through the feed pipe 901, it falls on the surface of the screening plate 17. Under the action of the fourth motor 20, the fourth motor 20 drives the cam 21 to rotate, and the cam 21 abuts against the lower surface of the screening plate 17. As the cam 21 rotates, the screening plate 17 is driven to vibrate up and down. During the vibration process, the spring 19 is repeatedly stretched, and the raw material falling on the upper surface of the screening plate 17, under vibration, the raw material of unqualified size rolls down on the other side and enters through the through slot 23. The raw materials are fed into the collecting box 22, which collects the unqualified raw materials. The qualified raw materials pass through the screening plate 17 and fall into the feeding channel 25. The staff controls the servo motor 28 through the PLC controller, so that the servo motor 28 drives the fourth rotating shaft 29 to rotate, and then the surface trough 31 of the rotating roller 30 rotates to the position just above. At this time, the raw materials that fall through the screening plate 17 pass through the second V-shaped funnel 24 and the feeding channel 25 and slide into the trough 31. When the trough 31 is full, the third motor 13 is turned off to stop feeding. The servo motor 28 rotates, and the servo motor 28 drives the rotating roller 30 to rotate. The excess raw material protruding from the circular groove 27 in the material trough 31 is scraped off, and the excess raw material remains in the feeding channel 25 above the rotating roller 30. When the material trough 31 on the other side of the rotating roller 30 rotates to the top, the raw material in the feeding channel 25 falls into the material trough 31, and then the third motor 13 is turned on to discharge the material again to fill the material trough 31. This process is repeated. When the material trough 31 rotates to the bottom, the raw material enters the mixing tank 1 through the feeding port 32. The rotation of the output end of the servo motor 28 is controlled by a PLC controller. According to the ingredient list and the storage volume of the material trough 31, the number of revolutions of the rotating roller 30 is accurately controlled, thereby controlling the amount of raw materials falling into the material troughs 31 in the mixing tank 1. Similarly, the remaining raw materials are added to the mixing tank 1 in the same way, thereby facilitating the control of the amount of material discharged. At the same time, the device can perform the screening process and the ingredient dosage of the raw materials simultaneously by screening the raw materials, thereby greatly reducing the working time and achieving the purpose of improving work efficiency.
